Method and system for pre-positioning wheel torque in a torque based vehicle speed control

摘要

A method and system for controlling an internal combustion engine upon initial entry into a speed control mode and upon transitions between dynamic operating modes of a speed control system includes means for determining an actual vehicle acceleration and means for determining an actual wheel torque. A controller determines an initial desired wheel torque based on the actual vehicle acceleration and the actual wheel torque and controls the torque generated by the engine based on the initial desired wheel torque so as to smoothly control the speed of the vehicle.
